How do I permanently disable all music and podcasts on my iPhone 6 Plus?

every time I plug my iPhone 6 plus into my cars system to charge the phone starts playing songs that must have been preloaded on the phone (e.g. u2) and I have to manually stop the music/podcast function. I find the album cover displayed to be disgusting as well. I have never used the music or podcast function and don't even want them.
